Polarizing plate and display device

Abstract

A polarizing plate of the present invention includes polarizing plate protective film(s) on one or both sides of a polarizer, wherein the polarizing plate protective film contains a compound represented by general formula (I) or (II) described below, the polarizer contains iodine, and the content of the iodine within the polarizer is 4.0 wt % or greater.

What is claimed is: 
     
       1. A polarizing plate comprising polarizing plate protective film(s) on one or both sides of a polarizer, wherein
 the polarizing plate protective film contains a compound represented by general formula (I) or (II) described below, and 
 the polarizer contains iodine, and the content of the iodine within the polarizer is 4.0 wt % or greater: 
 
       
         
           
           
               
               
           
         
         [in general formula (I), X represents a group represented by general formula (I-A-3) shown below; Z represents a benzene ring or cyclohexane ring; R 1  represents a substituent; n1 represents an integer of 2 to 6; and m1 represents an integer of 0 to 4; 
         in general formula (II), X represents a group represented by general formula (I-A-3) shown below; R 21  and R 22  each independently represent a substituent; n21 and n22 each independently represent an integer of 1 to 5; and m21 and m22 each independently represent an integer from 0 to 4; 
         in general formula (I), a plurality of Xs may be the same or different from each other; and when m1 is an integer of 2 or greater, a plurality of R 1 s may be the same or different from each other; 
         in general formula (II), a plurality of Xs may be the same or different from each other; when m21 is an integer of 2 or greater, a plurality of R 21 s may be the same or different from each other; and when m22 is an integer of 2 or greater, a plurality of R 22 s may be the same or different from each other; 
         General Formula (I-A-3) 
       
       
         
           
           
               
               
           
         
         in general formula (I-A-3), R C7  to R C12  each independently represent a hydrogen atom, an alkyl group, a cycloalkyl group, an aryl group, an acyl group, an alkoxy group, or an alkoxycarbonyl group; at least two among R C7  to R C12  may bond together to form a ring; and * represents a bond]. 
       
     
     
       2. The polarizing plate according to  claim 1 , wherein the polarizing plate protective film contains cellulose acylate. 
     
     
       3. A display device comprising at least one polarizing plate according to  claim 1 . 
     
     
       4. A display device comprising at least one polarizing plate according to  claim 2 .
